Petey A I can explain the delay in issue appearing.
"One interesting aspect of this phenomenon is that the sound doesn't fail immediately after an upgrade. In one case, it worked for nearly a day. But, inevitably, some program crashes on launch and I use ldd to discover that libjson.so.0 cannot be found." Notice when libjson.so 0.11.1 installs ldconfig does not run. But when you install libjson0_0.10-1.2_* it does run kinda straight away. It runs until the next item triggers the ld.so.cache rebuild. There is a delaying feature added to make update go in faster this is causing the effect you are seeing here. Ok this is bug 2. Will be digging how to force ld.so.conf to be updated straight away So bug does not lay hidden. Its not only libjson.so.0 bug that can lay hidden in a system to appear latter due to this with libc-bin delayed running of ldconfig being not always dependable. Once I have that I will run a few other tests and might have a better clue what is going wrong. Yes this is land mining. Peter Dolding
